Gauge: 1.25 Racquet: Head Microgel Extreme Pro Original Tension: 24kgs Surface: Clay Playing Style: Serve & volley / Agressive baseliner player with flat and little topspin shots. Expectations: I have great expectations about this string.. Since the first time i saw it on my racquet i knew it would be a nice experience. Power This category is not about the quality of the string.. It's all about how the power of the string adapts to your game. For me it was exceptional. I player a lot of S&V (even on clay) and it really suits my game, i was also getting high speed on my serves. A little faster than i use to serve. I was getting a lot of juice in my serves. 10/10 Control It was a great improvement to the 1.20 version.. At least for me. The 1.20 had great control but the 1.25 is unveliable. I attack the balls on the rise most of the time and with this string i could really swing into the ball with ridiculous accuracy. Feel Since the first hit i knew this was a winner. Never had a Poly with all this feel. I was feeling like i was playing with synthetic gut. My volleys were deep and i could really feel the ball penetrating the strings and releasing the ball to where i want them too. This is one of those feelings that you can only feel if you are playing. 10/10 Spin A little bit less than with the 1.20 Gauge. But that was expected. I'm not a very topspin person (only on serve and sometimes on the forehand). I'm more a slice person. I use it a lot. I was getting very good spin on my slices. They were deep, spinny and kinda like ''flowing'' in the air. 9/10 Durability/Tension Maintaince A lot of people that reviewed this string said this was the weakest point of the string. After a week of play with the 1.25 i can say that is the regular tension loss for a poly. 8/10 (9/10 for a poly) Comfort: Right... This string is very soft yet very crisp. I don't know how polystar made it possible but this string really takes the trophy here. With other polys (Alu, Redcode, SPPP) i had a little soreness in my wrist, elbow and shoulder and with polystar nothing.. I'm playing 3/4 hours a day with this string without problems. Overall I had great expectations for this string and it really lived up to that. My new standart string. I loved it. I felt like i was playing with synthetic gut the first time i played the string. If you are a player that is all about feel and touch, do youself a favor and go for it. Polystar just got themselves a new costumer. Do you know when you enter the Strings & Stringing section and you read some guy saying that 'xpto string' is the next big thing? I used to search about that string and maybe order a set or two. Now that i discovered polystar energy i don't care about trying new strings.. I just found the perfect string for my game and my wallet. I'm not seeing myself switching anytime soon. If you have an all court game or your game requires a lot of touch shots go for it. You won't be disappointed.
